Hence the name "Campo de Fiore". Later it was paved by Pope Callixtus III, creating the famous Roman San Pietrini. Over time, many important buildings were built in the surrounding area, making the square an obligatory place of passage for prominent personalities of that era such as Ambassadors and Cardinals. Did you know that the statue located in the center of the square is dedicated to a philosopher and Dominican friar called Giordano Bruno, who was burned alive by the Vatican on charges of heresy? In fact, over time the square also became the place where public executions were carried out!
